Natural flocculant for large pools in a bucket of 32 treatments
When the pool is large and the season is long, it is practical to have product for many weeks. The bucket of 32 treatments of Puerto Verde natural flocculant covers the weekly maintenance of a 50 m³ pool for more than seven months.
With a 100% natural formula, free of aluminum sulfate, it clumps together fine dirt that clouds the water and deposits it at the bottom so it can be removed with the pool vacuum.

Remember: flocculant does not remove algae
We want you to make the right purchase. This flocculant clarifies cloudy water, that which looks milky, dull, or lifeless. But green water is caused by algae, and flocculant does not work against them.
- Restores clarity to milky water.
- Sediments suspended dirt.
- Improves the performance of the filter and the pool vacuum.
- It does not destroy algae.
- It does not make the green color disappear.
- It does not replace the disinfectant or pH adjustment.
If your pool has turned green, the first thing is to get rid of the algae and balance the water. Once the green is gone, the flocculant takes care of the final turbidity. On our pool blog we explain the complete process.
How it works
From cloudy water to clear water
Presented in granulated powder, the flocculant is distributed throughout the pool thanks to the filtration system. Once in the water, it causes the suspended microparticles, too small for the filter, to join together and form heavier clumps. By stopping the filtration system, those clumps settle at the bottom and you just need to vacuum them up.
Distribution
The filtration system distributes the product.
Clumping
The microparticles form clumps.
Settling
With the water still, they fall to the bottom.
Vacuuming
The pool vacuum removes them.
Safety
Natural formula, without aluminum or sulfates
Aluminum sulfate is the basis of many flocculants on the market. Puerto Verde opts for a 100% natural formula, without aluminum and without sulfates. Thanks to this, it can be handled safely and is suitable for the whole family to bathe in, also for people with sensitive skin or chemical sensitivity, and it is not harmful to animals. A consistent option if you want an ecological pool.

Natural maintenance
Combine it with the natural range for pools
Well-balanced water stays clear for longer. The key is alkalinity: when it is in its optimal range, approximately 80-120 ppm, it buffers pH variations, the water becomes more stable and the flocculant works under ideal conditions.
